The present invention relates to an absorbent surface cleaning pad, such as a floor cleaning pad, and to a method for fabricating the surface cleaning pad in such a way as to provide zoned absorbency.
Conventional floor mops comprise a handle rotatably connected to a mop head and a disposable absorbent cleaning sheet coupled to the mop head. One side of the disposable absorbent cleaning sheet is placed in direct contact with a surface to be cleaned and the opposing side of the cleaning sheet is coupled to the mop head. The cleaning sheet absorbs and retains fluids, and loosens and traps dirt particles on the cleaning surface.
The cleaning sheet may comprise an absorbent portion that includes superabsorbent polymer (SAP) particles. The SAP particles can escape from the absorbent portion during manufacture, shipment, and normal use conditions. This phenomenon is commonly referred to as particle shake-out. A reduction in the amount or volume of SAP particles within the cleaning sheet hinders the performance and decreases the absorbency rating of the cleaning sheet.
Attempts have been made to overcome this problem in other fields such as the field of baby diapers, adult incontinence products, sanitary napkins and the like. For example, an absorbent structure for such products is disclosed in U.S. Pat. No. 6,562,742, which illustrates a diaper absorbent body with SAP particles placed in discrete locations or zones within the structure. According to the disclosure of U.S. Pat. No. 6,562,742, which is incorporated herein by reference in its entirety, superabsorbent polymer particles are placed in at least one strata of an upper ply in longitudinal discrete lanes along the length of the core, and the lanes are separated by adjacent lanes including fibers and a binder. Such a discrete placement of SAP particles is disclosed to allow for better containment of the particles, facilitate flow of liquid in the Z-direction because of the presence of areas with little or no SAP, and allow for easier flow and wicking of the fluid along the length of the core (x-direction). The areas with little or no SAP particles may be additionally densified to improve integrity and create higher capillary tension within smaller pores.
Nevertheless, there continues to be a need for an improved absorbent cleaning pad, such as a floor cleaning pad, and an improved method for fabricating the cleaning pad in such a way as to provide zoned absorbency.
According to one aspect of the invention, a surface cleaning pad is provided having a pad body with a cleansing surface configured for contact with a surface to be cleaned and an opposed surface configured to be coupled to a cleaning implement. The cleansing surface and the opposed surface together define a thickness of the pad body. The surface cleaning pad also has superabsorbent polymer particles maintained within a zone of the pad body. The zone of the pad body occupies the thickness of the pad body and an area that is contiguous yet less than that of the cleansing surface.
According to another aspect of the invention, a method is provided for forming a surface cleaning pad body having a matrix web of binder fibers and superabsorbent polymer particles. The method includes depositing a mass of binder fibers onto a conveyor. All but a selected area of the mass of binder fibers is shielded, and superabsorbent polymer particles are deposited onto the selected area of the mass of binder fibers so as to disburse superabsorbent polymer particles throughout a thickness of the mass of binder fibers. The mass of binder fibers is formed into a web structure that substantially contains the superabsorbent polymer particles, thereby providing a cleaning pad body with superabsorbent polymer particles substantially contained in a zone of the mass of binder fibers that occupies the thickness of the mass of binder fibers and the selected area. An attachment device is applied to the cleaning pad body, thereby configuring the pad body for attachment to a cleaning implement.
According to yet another aspect of the invention, a method is provided for forming cleaning pad bodies. The method includes forming a substrate of fibers. Superabsorbent polymer particles are applied to the substrate in zones extending along the substrate separated by a gap extending along the substrate. The substrate is parted along the gap to form substrate portions each having an edge portion substantially devoid of superabsorbent polymer particles. The substrate is parted substantially perpendicular to the gap to form cleaning pad bodies.
Exemplary embodiments of the invention will be described with reference to the drawings, of which:
Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention. Also, the embodiments selected for illustration in the figures are not shown to scale and are not limited to the proportions shown.
As used herein, the term “superabsorbent polymer (SAP) particle” refers to any absorbent material having a g/g capacity for water of at least about 20 g/g, when measured under a confining pressure of 0.3 psi. Non-limiting examples of suitable superabsorbent materials include water insoluble, water-swellable superabsorbent gelling polymers which are described in U.S. application Ser. No. 09/831,480, the disclosure of which is incorporated herein by reference in its entirety.
Referring to the overall structure of one exemplary embodiment,
More specifically, the exemplary absorbent cleaning pad (or sheet) 110 is provided with an airlaid composite 120. Two folded dirt entrapment members 125 are adhered to a cleaning side 152 of the airlaid composite 120 by an adhesive 130 and extend along the length of the airlaid composite 120. A barrier layer 140 is adhered to an opposing attachment side 155 of the airlaid composite 120 and is folded around the width-wise sides 124 of the airlaid composite 120, thereby enclosing the width-wise sides 124 of the airlaid composite 120. Two attachment members 145 are adhered to the barrier layer 140 by an adhesive 130.
The airlaid composite 120 of the exemplary embodiment absorbs and retains fluids and/or other matter residing on a cleaning surface. The cleaning side 152 of the cleaning pad 110 is in direct contact with the floor surface, and the opposing attachment side 155 of the absorbent cleaning pad 110 is in contact with a cleaning implement such as a mop head (not shown). The dirt entrapment members 125 serve to facilitate the removal of soils from the surface being cleaned by contacting and trapping larger soil particles. The barrier layer 140 substantially prevents fluid from passing from the airlaid composite 120 to the cleaning implement, to keep the cleaning implement substantially free of fluid. The barrier layer 140 also substantially prevents absorbent particles within the airlaid composite 120 from escaping out of the exposed width-wise sides 124 of the airlaid composite 120.
The attachment members 145 provide a single attachment mechanism that can be used to temporarily couple the absorbent cleaning pad 110 to a cleaning implement such as a mop head. In this exemplary embodiment, the attachment members 145 are composed of loop fastening material available from Velcro USA Inc. of Manchester, N.H., USA. Additional benefits and features of attachment mechanisms are disclosed in U.S. application Ser. No. 11/241,438, filed concurrently herewith. The disclosure of U.S. application Ser. No. 11/241,438 is incorporated herein by reference in its entirety. Also, benefits and features of additional optional components, such as cuff components, are disclosed in U.S. application Ser. No. 11/240,949 and U.S. application Ser. No. 11/241,437, filed concurrently herewith, which are incorporated herein by reference in their entirety.
The exemplary embodiment of the absorbent cleaning pad 110 comprises a unitized airlaid composite 120 having an absorbent core composed of at least binder fibers, absorbent fibers and superabsorbent polymer (SAP) particles 150. The absorbent core should be of sufficient integrity to ensure that the absorbent core does not deform and exhibit discontinuities during its normal use in cleansing a surface. The SAP particles 150 provide the airlaid composite 120 with increased absorbency, while the binder and absorbent fibers form the overall structure of the airlaid composite 120. In this embodiment, the binder fibers are optionally bi-component fibers and the absorbent fibers are optionally cellulosic fibers.
The absorbency portion of the airlaid composite 120 may optionally be composed of pulp fibers, rayon fibers, superabsorbent fibers, a combination of superabsorbent and pulp fibers, a combination of superabsorbent and rayon fibers, a combination of pulp, superabsorbent and rayon fibers, a non-woven web and a in-situ (liquid) superabsorbent, a tissue and in-situ (liquid) superabsorbent, a pulp and in-situ (liquid) superabsorbent, rayon fibers and a in-situ (liquid) superabsorbent, pulp, rayon fibers and a in-situ (liquid) superabsorbent, or a combination thereof of any of the above. The absorbent core component is an essentially hydrophilic material capable of absorbing and retaining fluids. The absorbent component may be composed of fibers, powders, and polymeric binders, any of which may be natural or synthetic.
The exposed sides of the airlaid composite 120 may be sealed or covered to substantially limit the SAP particles 150 from escaping out of the exposed sides of the airlaid composite 120. According to exemplary embodiments of this invention, however, to prevent the escapement of the SAP particles 150, the SAP particles may be concentrated or zoned an adequate distance away from one or more of the exposed sides of the airlaid composite 120. The matrix web of binder fibers would substantially inhibit the zoned SAP particles from migrating a significant distance toward the exposed sides of the airlaid composite 120. An example of a zoned SAP region is illustrated in
Additional benefits and features of an airlaid composite construction are disclosed in U.S. application Ser. No. 11/240,929, filed concurrently herewith. The disclosure of U.S. application Ser. No. 11/240,929 is incorporated herein by reference in its entirety.
In addition to airlaid composites, other absorbent pad body materials, structures and/or processes are contemplated as well. For example, in another exemplary embodiment an absorbent core prepared by expanding a polymer tow, disclosed in International Publication No. WO 2004/017883, is also contemplated for use as an absorbent pad. The disclosure of International Publication No. WO 2004/017883 is incorporated herein by reference in its entirety. In this exemplary embodiment, the absorbent core comprises a plurality of filaments in the form of an expanded tow, and a layer comprising a liquid superabsorbent material on surfaces of the filaments. The liquid superabsorbent polymer may be applied to the expanded tow, for example, by spraying or by application using a gravure roller. In this embodiment, the liquid superabsorbent polymer is applied to a portion(s) of the width and/or the length of the expanded tow.
Referring now to
The SAP particles 150 are also substantially prevented from escaping through the cleaning side 152 and the attachment side 155 of the airlaid composite. The dense web of binder fibers at the cleaning side 152 and the attachment side 155 of the airlaid composite substantially prevents the SAP particles 150 from escaping. In addition, the barrier layer 140 substantially prevents the SAP particles 150 from escaping out of the attachment side 155 of the airlaid composite 120, as illustrated in
The exemplary embodiment provides several advantages. The zoned SAP particles reduce particle shake out, gel blocking, and manufacturing costs and promote efficient fluid absorption throughout the airlaid composite. SAP particle shake-out hinders the performance of the cleaning pad and degrades the cleaning pad's absorbency rating. By virtue of the zoned SAP, the exemplary cleaning pad 110 can retain a greater number of SAP particles within the airlaid composite.
The discrete placement of SAP particles also facilitates the flow of fluid along the regions of the cleaning pad devoid of SAP particles. The regions without SAP particles promote flow and wicking of fluid along the entire length and width of the exemplary airlaid composite. Therefore, the discrete placement of SAP particles promotes the utilization of the entire airlaid composite for absorption.
The discrete placement of SAP particles also substantially reduces gel blocking within the airlaid composite, thereby improving the cleaning pad's ability to absorb and retain fluid. Gel blocking leads to the inhibition of fluid flow throughout the entire airlaid composite, thereby reducing the absorbency rating of the cleaning pad. In other words, the airlaid composite cannot efficiently absorb fluid if too many SAP particles are positioned or concentrated on the cleaning surface of the airlaid composite, as the swelled SAP particles prevent the fluid from traveling in the z-direction (i.e., along the thickness of the airlaid composite). The discrete placement of SAP particles promotes uniform fluid absorption throughout the exemplary airlaid composite.

Although only one example of an airlaid composite forming system is illustrated, this invention is not limited to the particular airlaid composite forming system selected for illustration in the Figures, and this invention is not limited to an absorbent pad having an airlaid structure. Other airlaid forming systems and other pad-producing processes are contemplated as well.
The airlaid composite forming system 600 comprises a moving perforated forming wire 602, which acts as a conveyor, with forming head equipment mounted thereabove. In the orientation illustrated in
Forming heads 604 and 606 each receives a flow of an air fluidized fiber material (e.g., binder fibers, wood pulp, other fibrous materials, or combination thereof) via supply channels 608. A suction source 614 mounted beneath the perforated moving wire 602, draws air downwardly through the perforated moving wire 602. In one embodiment, the binder fiber material is distributed and compacted (by the air flow) over the width of the wire 602 to form an light web layer on the surface of the wire 602. A second forming head (not shown) is provided to distribute a second web layer 616 composed of a mixture of binder fibers and cellulosic fibers onto the light web layer.
The SAP particles are introduced into the particle dispenser 620 through a tube 618. The particle dispenser 620 is configured to direct (e.g., spray, sprinkle, release, etc.) the SAP particles onto the perforated moving wire 602 above the web layer 616. The SAP particles are either distributed over a portion of the width and/or length of the web layer 616 or distributed over the entire web layer 616. The SAP particles blend and disseminate through the web layer 616 and are thereby maintained throughout the entire thickness of the airlaid composite.
A third forming head 606 is provided to distribute another web layer 622 of binder and/or cellulosic fibers over the SAP particles. Although only two forming heads are illustrated, more forming heads may be required to distribute additional layers of binder fiber or cellulosic fiber. Thereafter, the web layers are heated for a period of time until the binder fibers melt together to form a web-like structure, i.e., an airlaid composite.
In functional terms, the first light web layer including binder fibers is oriented toward the cleaning surface and provides structure to the airlaid composite. The second web layer 616 including binder fibers and cellulosic fibers is maintained over the first light web layer and provides structure and absorbency to the airlaid composite. The SAP particles are maintained over the second web layer 616 to provide additional absorbency to the airlaid composite. The third web layer 622 including binder fibers and cellulosic fibers are maintained over the SAP particles and is oriented toward the cleaning implement. The third web layer 622 provides structure and absorbency to the airlaid composite. The web layers collectively form an airlaid composite according to one embodiment.
Although not shown, in yet another exemplary embodiment, a preformed sheet comprising SAP particles may be positioned above the light web layer 616, as an alternative to using the particle dispenser 620. The preformed sheet may be of any size equal to or smaller than the light web layer 616.

As an alternative to configuring the particle dispenser 620 to distribute the SAP particles over the segment “F” of the web layer 616, a screen may be positioned above the web layer 616 to limit the placement of the SAP particle zone 550 to a segment “F” of the web layer 616. In this exemplary embodiment, the particle dispenser 620 is configured to distribute the SAP particles over the entire web layer 616, although the screen limits the distribution of the SAP particles to the segment “F” above the web layer 616.
While preferred embodiments of the invention have been shown and described herein, it will be understood that such embodiments are provided by way of example only. Numerous variations, changes and substitutions will occur to those skilled in the art without departing from the spirit of the invention. Accordingly, it is intended that the appended claims cover all such variations as fall within the spirit and scope of the invention. Also, the embodiments selected for illustration in the figures are not shown to scale and are not limited to the proportions shown.
